2. Description of the Related Art It has been known that an amine imide compound undergoes a transfer reaction upon heating and is decomposed to produce an isocyanate compound and a tertiary amine. The generated isocyanate compound reacts with an organic compound having a hydroxyl group, an amino group, or the like, to thereby generate polyurethane or polyurea. It is known that the tertiary amine produced can be applied as a curing agent for epoxy (J. Appl. Polym. Sci., 27,

As described above, the amine imide has been studied as a thermal crosslinking agent for an epoxy resin. However, the decomposition usually requires a temperature of 130 ° C. or more. However, there is a disadvantage that it cannot be used for a heat-sensitive adherend. Therefore, studies are being made to lower the decomposition temperature of the crosslinking agent and cure the epoxy resin at a lower temperature. Among the amine imide compounds known to date, those which can cure an epoxy resin by heating at 100 ° C. or higher include those disclosed in

8, 20 parts by weight of talc as a filler and 0.5 to 60 parts by weight of the amine imide according to the present invention shown in Example 6 as a curing agent for 100 parts by weight of Yuka Shell Epoxy Co., Ltd. , And the mixture was stirred to prepare a uniform one-part epoxy resin composition. Then, the adhesive strength of each of the compositions to the iron plate was measured. The curing conditions of these epoxy resin compositions were set at 150 ° C. × 3 hours using a constant temperature drying oven. Other conditions were in accordance with JIS-K6850. Table 5 shows the results.

As described above, it was confirmed that the amine imide of the present invention was obtained. In addition, this amine imide is decomposed at a low temperature, and by using it as a curing agent for epoxy resin, it has the same or better low-temperature curability and rapid curability than conventional ones, and is a one-pack type with less coloring of the cured product. An epoxy resin composition was obtained.
